NELSON W. DINGWALL AND CLIFFORD M. BUDD, OF NEW YORK, N. Y.

ADAPTER AND BOOSTER CASING FOR SHELLS.

Application filed July 2c, 1918.

To all whom it may concern:

Be it known that we, NELSON W. DING- WALL and CLIFFORD M. BUDD, citizens of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Adapter and Booster Casings for Shells, of which the following is a specification.

This invention relates to shells or projectiles and has particular reference to an adapter and booster casing therefor.

It is the purpose of the present invention to provide an adapter and booster casing for shells which comprises a minimum number of parts and is simple in structure, so that the number of operations necessary in manufacturing the structure is relatively small and therefore the rate of production can be increased and the cost of making very materially decreased. The adapter and booster casing are made integral with each other, so that the expense and waste in performing certain operations to connect theseparts when they are made separately, as is now usual, are entirely eliminated, and since, in our new structure, there are no joints between the adapter and booster casing, the gas within a gas shell cannot escape into the adapter and then pass from the head and constitute a source of danger to persons handling the shell. The internal bore of the adapter and the chamber of the booster casing are of like diameter throughout their lengths and are provided with a single screw thread for the reception of both the fuse socket holder and the threaded nipple of the fuse body, and thus the operations of counter boring the adapter and making a separate fuse bushing for maintaining the fuse holder in place, and which operations are necessary in making adapters and booster casings as heretofore constructed, are done away with. The operation of filling the booster casing of our structure with an explosive charge can be readily carried out.

The above and other objects of our invention are obtained in the structure described in the following specification and illustrated in the accompanying drawings, and wherein Figure 1 is a longitudinal sectional view through our improved adapter and booster casing, the fuse body and a portion of the shell being shown in dotted lines.

Fig. 2 is a sectionalview taken on line 22 of Fig. 1.,

Serial No. 246,896.

Fig. 3 is an enlarged sectional view of the fuse socket and holder therefor.

In said drawings, the numeral 10 designates the. adapter, which is externally threaded as at 11, so as to be screwed into the threaded opening in the nose of the shell'or projectile 12. 'In the present instance we have shown the thread 11 as being in the form of a tapering pipe thread, and while such a thread is of particular utility in the event the adapter is used in connection with a shell containing gas so as to prevent the leakage of gas from theshell, it is, of course, understood that this thread may be varied,

as desired, and in cases where the shell contains a high explosive instead of a gas, the

diameter of the nipple 15 of the fuse body 7 16 and is threaded to directly receive the nipple so that the use of the bushing which is now usually employed between the adapter and the nipple of the fuse, is eliminated.

Formed integrally with the adapter 10 is a booster casing 17 The booster casing 17 is cylindrical in cross section and is closed at its lower end, as is usual, but in the present instance the diameter of the chamber 18 of the booster casing is of like diameter as the uniform bore 14 of the adapter, so that the chamber 18 and the bore 14 form, in effect a single chamber which is devoid of shoulders or the like. The diameter of the bore 14 and, therefore, the diameter of the chamber 18 will depend upon the size of the threaded nipple of the fuse body 16.

The thread 19 of the bore of the adapter extends for some distance downwardly into the chamber 18, so that the fuse socket, holder, which in the present instance consists of an externally threaded ring 20, may be screwed into place, it being understood that the nipple 15 and the ring 20 are of the same external diameter and are similarly threaded. The fuse socket, which is designated by the numeral 21, comprises a thimble-shaped member, formed by pressing or dravvin'g'a sheetof "thin metal to the proper shape. The fuse socketholder lm'is provided with sockets '24 t o receive means by which it may be rotated While engaging the thread 19. V
